In the end we canceled the PH and stayed in The Alvear Palace as they accommodated every request i asked for before we arrived including a discount and an upgrade to a descent size suite . The hotel felt like a Palace, stunning and service was better then any st regis i have visited. The walk was around 8 minutes to chabad of Recoleta, They have Shabbat locks, and the walk to Chabad Friday night meal is 60 seconds from hotel. As Dan mentioned before This was the best chabad food we have experienced!
